Most PAL DVD Players will playback an NTSC movie fine, assuming its also Multiregion unit. If the DVD is a single layer DVD5, then simply ripping with DVD Decrypter in ISO mode and then burning back will remove all Region settings (as well as encryption & macromedia). If its an old TV, it may not appear in colour, thats all. Then you will have to convert it, just follow the DVD to DVDR Tutorial and tick the NTSC to PAL box.
